Originally posted by Pentaxor looking for data regarding damage resistance would be hard to find since I dont think that people would generally document such incidents nor intently do so. googling up personal case scenarios might give you the data that you are looking for.
anyway, fwiw, I think I saw an old post in this forum where a damaged K20D was sold due to a fall and a picture of it was provided to show the extent of the damage. I think I had also read some old posts describing how their K10 or K20D were replaced because their camera cracked when their cameras accidentally fell.
I have no doubt that a K20D's body will crack with a hard impact; I have little doubt (although I'm not certain; no data) that a K-7's body will stay in one piece under the same conditions. The question is, of course, will it still work? Whether the camera is incapacitated by a cracked body or by internal damage seems rather academic.
The only simple (but expensive) way to sort this out would be to do some controlled drop tests with multiple examples of the two bodies (with identical lenses mounted, at the same time, same temp., etc.). No one is going to do this, of course. For one thing, it'd be expensive to sacrifice a bunch of camera bodies to get to the answer. Secondly, Pentax and its customers might not like the answer, so why ask the question?
Anyway, the K-7 is a very cool camera, and I suspect few people will feel like slinging one into a concrete wall to see if it breaks. As the price has dropped, I've been sorely tempted to buy one myself, but I'm still inclined to wait for the next iteration. My personal experiment is to determine if I'll hold out!
